CORN-HUSKING ROLLS.

Specification of Letters Patent.

Patented Dec. 10, 1907.

To all whom it may concern:

Be it known that I, AUGUST RosENTHAL, residing in Vest Allis, in the county of Milwaukee and State of IVisconsin, have invented new and useful Improvements in Oorn-Husking Rolls, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in corn-husking rolls.

In corn-husking rolls as commonly constructed, the upper ends of the rolls constitute the snapping portions of said rolls, While the remaining portions of the rolls are the husking portions thereof. In view of the fact that the stalks are initially fed to the upper snapping portions of the rolls and the ears are snapped off by the action of these upper portions of the rolls, there is more wear at said upper portions than at the remaining or husking portions of the rolls. In consequence, the ribs or projections of the snapping portions soon become worn and their efficiency thereby greatly impaired. `When so impaired, the entire roll is rendered worthless, and it is necessary to substitute a new roll therefor.

It is one of the main objects of my present invention to form the snapping ribs and other parts of the snapping portions of the rolls on a separate sleeve which is removably keyed on to the end of the aXis of the roll, so that when the snapping ribs, or other parts, become worn, the entire sleeve may be slipped off, and a new sleeve substituted, without the necessity of supplying an entirely new roll. Also, in the use of husking rolls short pieces of stalks are frequently not carried between the snapping portions of the rolls and slide down the rolls with the ears of corn on to the husking portions of said rolls; and in husking rolls as now commonly constructed no means are provided for carrying these short pieces of stalks between the husking portions of the rolls, and consequently they slide off the ends of said rolls with the husked ears of corn.

A further object of my invention, therefore is to so construct the husking portions of the rolls that provision is made for carrying the short pieces of stalks between said husking portions of the rolls, and thereby preventing said short pieces of stalk from sliding off the ends of the rolls with the husked ears of corn.

With the labove primary objects in View, the invention consists of the devices and parts, or the equivalents thereof, as hereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a plan view of husking rolls equipped with my improvements; Fig. 2 is a longitudinal section through the snapping end of one of the rolls, and through a fragment of the husking portion of said roll; Fig. 3 is a cross section on the line 3 3 of Fig. 1, and Fig. 4 is a cross section on the line 4-4 of Fig. 1.

In corn-husking machines, as is well understood, the husking rolls are usually arranged in the frame of the machine on a gradual declination from the front end of the machine to the rear thereof, and the rolls are geared together so that the rolls of each pair will rotate towards each other. The cornstalks are fed to the upper snapping ends of the rolls, and at these portions of said rolls the ears are snapped off and the separated stalks pulled between and below the rolls, usually to cutting and shredding mechanism, while the severed ears of corn slide down the inclined rolls on to the husking portions thereof, where they are acted upon by the husking pins and stripped of their husks, the said husks passing between and below the rolls, and the husked ears sliding off the rear ends of said rolls. It is in connection with this form of husking machine that my' improved rolls are more especially ada ted. In the accompanying drawing I have s own four of the rolls, although of course only one pair may be provided, or more than two pair, in accordance with the capacity of the machine.

Referring to the improved rolls, the numerals 5 indicate sleeves which are fitted on to the upper ends of the rolls, which constitute the snapping portions of said rolls; 6 indicates the husking portions of the rolls, and 7 the aXes of the rolls. The circumferential surface of each inner sleeve 5 is provided at diametrically opposite points with recesses 8, 8, extending longitudinally of the sleeves. The surface of the sleeve of each outer roll is provided longitudinally with a pointed projection 9, whichas the rolls of a pair are rotated in the direction of the arrows Fig. 3, are adapted to enter the recesses 8 of the inner roll, and thereby have the effect of kinking or breaking the stalks and thereby assisting in pulling or snapping the ears off the stalks and permitting the stalks to pass between the rolls. The surface of the sleeve at the snapping portion of each outer roll is also provided circumferentially with ribs or projections 10 which are adapted to grasp or take hold of the stalks and pull them between the rolls. For the purpose of holding each sleeve in place on the end of the roll, the axis of the rollis rovided witha key 11, which is adapted to t a corresponding groove in the sleevesaid groove extending to the end of the sleeve, so that when it is desired to remove a sleeve, it can be' pulled outwardly with force.

As stated at the outset of the speciiication, the ribs and other parts of the snapping portions of husking rolls have heretofore been formed integral with the rolls, and this construction in practice has been found objectionable owing to the fact that the ribs and other parts become worn to such an eX- tent as to seriously interfere with the proper work of the snapping portions, and consequently it has been necessary to remove the entire roll and substitute a new one therefor. By my improved construction, however, where the ribs and other parts of the snapping portions of the rolls are formed on a separate sleeve slidably iittedto the upper portions of the rolls, the diiiiculty referred to is obviated, inasmuch as when. the ribs or other parts become worn, the sleeve may be entirely removed and a new sleeve substituted, without the necessity of discarding the entire roll.

The husking portions of my improved rolls are shown as provided circumferentially with recesses 12. These recesses not only serve to lighten the rolls by the removal of unnecessary metal, but furthermore serve in the operation of the rolls to tear off the points of nubbins and permit the husks Ito pass between the rolls. In a number of these recesses of the outer rolls are disposed the husking pins 13.

The important feature of construction .of the husking portions of the rolls is the provision of a groove 14 extending longitudinally of said husking portion of each roll. The grooves of each pair of rolls, as the said rolls are rotated towards each other, are adapted at one point of the revolution to be brought together or into register, as clearly shown in Fig. 4.

In the use of husking rolls, short pieces of stalk frequently fail to vpass `between the snapping portions of the rolls, but slide down the rolls with the ears of corn on to the husking portions of said rolls, and instead of being carried between and below the husking portions of the rolls, they slide 0H the rear ends of said rolls with the husked ears of corn, and

svaeio this is particularly true when the stalks are hard or frozen. It is found in practice that by providing the husking portions of the rolls with these longitudinal grooves 14 the short pieces of stalk are caught by the grooves and are carried around therein between the rolls and discharged below the rolls.

lt will be seen that the ends of the rolls which receive the sleeves 5 are .tapered outwardly, and that the sleeves are correspondingly tapered. This provides a wedging fit of the sleeves on the ends of the rolls, and thereby assists Vin retaining said sleeves. The inner end of each sleeve bears against a shoulder 15 formed on each roll.

What l claim as my invention is:

1. A roll for a corn-husking machine, said roll at one end, for a desired distance, being smaller in diameter than the remaining major portion of the roll, whereby a shoulder is formed at the point of juncture between said two portions of the roll, the portion of the roll of greatest diameter provided with means for husking the ears of corn, and a continuous sleeve removably fitted to the reduced end of the roll and bearing at its inner end against the shoulder, said sleeve provided with means for engaging corn-stalks and separating said stalks from the ears.

2. A pair of rolls for a corn-husking machine, said rolls adapted to be rotated toward each other, and each roll at one end, for a desired distance, being smaller in diameter than the remaining major portion of the roll, whereby a shoulder is formed at the point of juncture between the said portions of the roll, the portion of the roll of greatest diameter provided with means for husking the ears of corn, and a continuous sleeve removably itted to the reduced end of each roll, and bearing at its inner end against the shoulder, the said sleeve provided with means for engaging the corn-stalks and separating said stalks from the ears.

3. A pair of rolls for a corn-husking machine, said rolls adapted to be rotated toward each other, and each roll at one end, for a de'- sired distance, being smaller in diameter than the remaining major portion of the roll, whereby a shoulder is formed at the point of juncture between the said portions of the roll, the portion of each roll of greatest diameter provided with means for husking the ears of corn, and a continuous sleeve removably fitted to the reduced end of each roll and bearing at its inner end against the shoulder, one of said sleeves provided longitudinally with a groove, and the corresponding portion of the other sleeve with a co-acting projection, the projection adapted to enter the groove and thereby break or kink the cornstalks, and cause the separation of the ears from said stalks.

4. A pair of rolls for a corn-husking machine, said rolls adapted to be rotated toward each other, and said rolls being provided circumferentially or transversely of the length thereof with recesses, one or more of said recesses provided with pins projecting from the bottom or bottoms thereof, the surface forming the separating walls between two lines of the recesses of each roll being in turn provided with a longitudinal recess, the said recesses of the two rolls being so disposed on the respective rolls as to meet, when the rolls are rotated toward each other.

5. A roll for a corn-husking machine, said roll at one end, for a desired distance, being smaller in diameter than the remaining major portion of the roll, whereby a shoulder is formed between the point of juncture of the said two portions of the roll, the said reduced end of the roll being tapered outwardly from the shoulder, and the portion of the roll of greatest diameter provided with means for husking the ears of corn, and a sleeve having a tapered bore removably Viitting the tapered end of the roll and bearing at its inner end against the shoulder of the roll, said sleeve provided with means for engaging the cornstalks and separating said stalks from the ears.

6. A roll for a corn-husking machine having one end tapered, and a sleeve having a tapered bore removably fitting said tapered end of the roll, and bearing `at its inner end against a shoulder of the roll, the exterior surface of said sleeve provided with stalkengaging means.

ln testimony whereof, I affix my signature, in presence of two witnesses.
